In this paper, we investigate the performance of iterative decoding for concatenated Turbo coded and Space-time block coded (STBC) system. In our proposed system the soft parity bit needs to be estimated, which differs from traditional Turbo decoding, as the receiver adopts iterative decoding not only to Turbo codes but the entire system. In this case a simplified and effective method of parity bit...
Hybrid MIMO scheme applies some of the transmit antennas with pure diversity schemes (e.g. STBC) while others with pure spatial multiplexing schemes (e.g. VBLAST), in order to achieve the diversity gain and multiplexing gain at the same time. However, the spatial multiplexing schemes without diversity gain are susceptible to the fading effect. In this paper, we propose an adaptive hybrid MIMO scheme...
In this paper, we show, in both theory and simulation, that by transmitting two real orthogonal space-time block codes (O-STBC) on the I- and Q-channels with pulse-shaped offset QAM, we are able to achieve full rate transmit diversity for a 4 times 1 system with very simple "half-symbol" detection, i.e., the real I- and Q-symbols can be separately decoded. For this scheme, two families of...
